VLBI observations in Cluster-Cluster mode at 1.6 GHz
M. J. Rioja, R. W. Porcas, J. -F. Desmurs +3
We describe, and present preliminary results from the analysis of 1.6 GHz VLBI observations, made in Cluster-Cluster mode between subgroups of antennas from the WSRT, VLA and MERLI…
Proper motion in Cygnus A
U. Bach, T. P. Krichbaum, W. Alef +2
Our recent VLBI observations of the prominent FR II radio galaxy Cygnus A with the EVN and the VLBA reveal a pronounced two-sided jet structure. At 5 GHz, we now have 4 epochs from…
2mm Wavelength VLBI of SiO Masers and AGN
S. Doeleman, R. Phillips, A. Rogers +21
In April 2002 an array of antennas operating at 129GHz successfully detected VLBI fringes on both continuum AGN and SiO maser sources. The 129GHz fringes on maser sources represent…
Searching for low mass objects around nearby dMe radio stars
J. C. Guirado, E. Ros, D. L. Jones +3
Nearby M-dwarfs are best suited for searches of low mass companions. VLBI phase-referencing observations with sensitive telescopes are able to detect radio star flux-densities of t…
VLBI observations at 147 GHz: first detection of transatlantic fringes in bright AGN
T. P. Krichbaum, D. A. Graham, W. Alef +21
At 147 GHz (2mm wavelength), we detected three prominent AGN (NRAO150, 3C279, 1633+382) with Very Long Baseline Interferometry (VLBI) with an angular resolution of only 18 micro-ar…
